If you look at
clip 3:57-3:59, you can see "
0" and "
1" or anytime the bullets hits tenshi's shield numbers come out. I'm not sure if anybody posted this or not but maybe this proves that tenshi was a computer wizz back in her previous life or she uses some computer language and coonected to this world.
Maybe somebody could use this info to back up there theory or build one up or this can add extra rules to there world
